Răspuns:
A)
[tex] \frac{4}{5x} - 2 = 2 \times \frac{1}{2x} - \frac{1}{5} x =taiat0[/tex]
[tex] \frac{4}{5x} - 2 = \frac{1}{x} - \frac{1}{5} [/tex]
[tex] \frac{4}{5x} - \frac{1}{x} - 2 = - \frac{1}{5} [/tex]
[tex] \frac{4}{5x} - \frac{1}{x} = - \frac{1}{5} + 2[/tex]
[tex] - \frac{1}{5x} = - \frac{1}{5} + 2[/tex]
[tex] - \frac{1}{5x} = \frac{9}{5} [/tex]
[tex] - 5 = 45x[/tex]
[tex]45 x= - 5[/tex]
[tex]x = - \frac{1}{9} .x = taiat0[/tex]
Solutie:
[tex]x = - \frac{1}{9} [/tex]
